pull stud

There is no pull stud with this type of tooling.

One other subtle difference between these two toolholders is the thread used to hold the pull stud.

Although the basic taper dimensions are the same, there are differences are in the flanges, draw-in thread sizes, and pull studs; the international versions use metric sizes.

Note that this affects the pull stud only, it does not affect the tool that they can hold, both types of tooling are sold to accept both Imperial and metric sized tools.
